Sample GSM3042018 Query DataSets for GSM3042018
Status Public on Apr 06, 2018
Title INS_A_beta_2
Sample type SRA
Source name EndoC βH1
Organism Homo sapiens
Characteristics cell type: Pancreatic beta cells
cell line: EndoC betaH1
Treatment protocol Cells were fixed by formaldehyde. The cross-linked chromatin was digested by BglII (New England Biolabs) and re-ligated by T4 DNA ligase (New England Biolabs). After reversal of crosslinks, DNA was digested by NlaIII (New England Biolabs) and re-ligated by T4 DNA ligase (New England Biolabs). The DNA product served as template for 4C-PCR.
Growth protocol EndoC βH1 cells were grown in were cultured in low-glucose Dulbecco's modified Eagle's medium (Life Technology, cat. # 11885) with 2% BSA (fatty acid free and heat shocked, Equitech, cat. #BAH66), 50 μM 2-mercaptoethanol, 10 mM nicotinamide, 5.5 mg/ml human transferrin (Sigma–Aldrich, cat. #T8158), 6.7 ng/ml sodium selenite, 100 U/ml penicillin, and 0.1 mg/ml streptomycin. Cells were seeded at a density of 6 × 105/cm2 on ECM-gel (1%) (Sigma-Aldrich, cat. # E1270) /fibronectin (2 g/ml; Sigma–Aldrich, cat #. F1141) coated plates and cultured at 37 °C and 5% CO2. Hela cells were grown in low-glucose Dulbecco's modified Eagle's medium with 10% Fetal Bovine Serum and cultured at 37 °C and 5% CO2.
Extracted molecule genomic DNA
Extraction protocol Phenol-Chloroform and ethanol precipitate.
Direct PCR from 4C library
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina HiSeq 2500
Description Pancreatic β cells
Data processing Library strategy: 4C-seq
Barcode sequences were removed from the reads.
The reads were mapped with Bowtie2 version2.2.
The reads mapped to the bait (self-ligation reads) were filtered out.
The remain reads were mapped with Bowtie2 again.
